for changing the direct currents in this instance into pulsatory currents. The rheotome D here shown is adapted to revolve at a high rate of speed, being driven in any convenient manner-as, for instance, by an engine or by an electric motor, E, operated by currents derived from a portion of the storage-battery through the conductors e and e, or in. any other convenient manner. The rheotome may .consist of two rings or plates, (1 and 01 having teeth or plates (1 and d* alternating wit-h each other. The conductor bis connected with one of these plates through a brush, f, which rests continuously upon the ring d. The line L is connected with the brush t, which makes alternate contact with the two plates through the alternating teeth. The plate d is connected with the plate d or the line L through an artificial resistance, It. The line L is connected with the other pole of the battery through a conductor, b In this manner the battery will be connected with the line L L first directly and then through a resistance, and a pulsatory current will be transmitted. This current will be converted into secondary or induced currents by the converters G and C. In this manner the translating devices may be operated by the energy derived from the battery B.

In case the currents are desired to assist the generator A, it will be necessary that the changes in it should be synchronous or coincident with the changes in the current delivered by the generator. For this purpose it may be desirable to place the rheotome upon the shaft of the generator A. as indicated in Fig. 2. The electric motor E will then be dispensed with. as a rheotome for reversing the connections of the battery 13 coincident with the reversals in the direction of the en rrent from the generator A. For this purpose the conductors 3 and 4, leading from the poles of the generator A, may be opened and the brushes a and a connected, respectively, with the conductors L and L by switches S and S The alternations will then be synchronous and in unison with those of the generator.

In some instances the current delivered by 3' the generator A may not be of the proper electro-motive force for charging the battery to the best advantage. In such a case it may be desired to employ a converter, 0, Fig. 3, for transforming the currents as may be required. To this end the conductors3 and 4, leading from the conductors 1 and 2', may be connected through the primary coils p of the converter 0, and the secondary coils care then connected with conductors 5 and 6,leading to the brushes a and a of the rectifier. The coils p and s are so proportioned as to transform the currents as may be required.

The current from the storage-battery may be made intermittent instead of alternating or pulsatory in the manner also shown in Fig. 3. In this instance connection from one pole of the storage-battery is made through In this instancethe rectifier A serves the conductor 'b with the brush f, applied to an interrupter, D. The-brush t is connected with the line L. The other pole of the battery is connected by a conductor, b with the line L The interrupter D consists of a ring of conducting material having non-conductingv 2. The combination, with a system of elec tric distribution operated by alternate, intermittent, or pulsatory electric currents, of a storage-battery, means for charging the same by currents from the source of supply of said system, a rheotome for rendering discontinuous the currents from the battery, means for driving the same, and connections from the rheotome with said s'ystem,substantiall y as described.

3. The combination of a source of alternate electric currents, a system of secondary distribution operatedby currents therefrom, a storage-battery, a converter for changing the potential of currents derived from the said generator, and a current rectifier connected with the converter and delivering rectified currents to the storage-battery.

4. The combination, with a source of alternating, intermittent, or pulsatory electric currents and a work-circuit supplied therefrom, of a storage-battery,a current-rectifier through which currents are delivered from said source to said battery, a system of secondary distribution operated by currents from the generator, and a rheotome for rendering pulsatory, intermittent, or alternating currents from said battery and delivering them to said system of distribution, said rheotome moving synchronously with said generator, substantially as described.

5. The combination, with a source of alternating, intermittent, or pulsatory electric currents and a work-circuit supplied therefrom, of a storage-battery,a current-rectifier through which currents are delivered from said source to said battery, a system of secondary distri-. bution operated by currents from the generator, and means for connecting said storagebattery with the work-circuit through said rectifier.
